I. Applicable railways: Usually applicable to multiple railway types such as ordinary railways and urban rail transit. However, on some high-speed or heavy-haul railways with special requirements for fastening performance, its applicability may need to be further evaluated.
II. Applicable gauge: Generally applicable to railway tracks with a standard gauge of 1435 millimeters. For other non-standard gauges, customization or adjustment may be required.
III. Advantages and disadvantages
1.Advantages:
Moderate clamping pressure: It has a certain clamping pressure, which can effectively fix the rail on the sleeper, ensure the stability of the rail, reduce the longitudinal and lateral displacement of the rail, and ensure the safety and smoothness of railway operation. Its clamping pressure is usually within a certain range (for example, the clamping pressure of the French NABLA spring clip fastening is 11kN).
Good elasticity: When a train passes, it can provide a certain elastic buffer, absorb vibration energy, reduce the impact of vibration on the track structure, and improve the comfort of train operation. And the elastic stroke is also relatively reasonable.
Has a certain gauge adjustment ability: It can adjust the gauge to a certain extent to adapt to different line requirements and rail thermal expansion and contraction.
Relatively easy installation: The structural design is relatively simple. During the installation process, no complex tools and processes are required, which can improve installation efficiency and save construction time and cost.
2.Disadvantages:
Fatigue problems may occur after long-term use: Like most metal spring clips, under the long-term action of train loads and after multiple compressions and rebounds, fatigue phenomena may gradually appear, leading to a decline in the performance of the spring clip, such as weakened elasticity and reduced clamping pressure. Regular inspections and replacements are required.
The gauge adjustment range is limited: Although it has the gauge adjustment function, compared with some specially designed gauge adjustment fastenings, its adjustment range may be relatively small. For some special cases with large gauge changes, it may not meet the requirements.
There are certain requirements for environmental adaptability: In some harsh environmental conditions, such as high temperature, low temperature, humidity, corrosion, etc., the material of the spring clip may be affected, resulting in changes in its performance and a shortened service life. Corresponding protective measures need to be taken to ensure its normal use.
IV. Product material:
Generally made of metal materials with high elasticity and strength such as spring steel to meet the requirements of clamping the rail and withstanding train loads.
